The invention relates to a method for extracting .beta.-glucan from cereals. The extraction is carried out using wetted cereals by adjusting the pH thereof to a value below 5.2 with an acid, and further, by treating the cereal in an enclosed space under pressure less than about 5 bar, at a temperature of 100 - 130~C. After the treatment, the liquid phase is separated from the solid material, followed by recovery of .beta.-glucan from this separated aqueous phase.

L'invention se rapporte à un procédé d'extraction d'un .beta.-glucane à partir de céréales. L'extraction est effectuée en utilisant des céréales humidifiées en ajustant leur pH à une valeur en dessous de 5,2 avec un acide et, en outre, en traitant les céréales dans un espace clos sous une pression inférieure à environ 5 bars, à une température de 100 à 130 ·C. Après le traitement, la face liquide est séparée de la matière solide, ce qui est suivi par la récupération de .beta.-glucane à partir de cette phase aqueuse séparée.
